(54) Starting device of passenger protection apparatus


(57) A starting device of a passenger protection apparatus has a hollow body (11) defining a cavity in which a fluid exists, a current speed measuring means (12) and a determination means (13). The current speed measuring means (12) is disposed to allow the cavity of the hollow body (11) to communicate with a space outside of the hollow body (11). The current speed measuring means (12) measures a current speed of the fluid passing therethrough when a differential pressure occurs between the cavity of the hollow body (11) and the space outside of the hollow body (11) at least due to a collision. The determination means (13) determines the collision based on the current speed measured by the current speed measuring means (12).
